APPARATUS FOR UNITING WOOD FOR FLOOR-COVERINGS.

SPECIFICATION forming partof Letters Patent No. 320,616, dated June 23, 1885.

Application filed May 10, 1884. (No model.)

To all whom it may concern:

Be it known that I, HENRY BEISHEIM, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Apparatus for Uniting Wood for Floor-Coverings, 850., of which the following is a specification. reference being had to the accompanying drawings.

My invention relates to certain improvements in apparatus for uniting grooved blocks of wood or other material for floor-coverings, 820., by the introduction of molten metal or a suitable alloy into grooves around the'sides of the blocks, according to the method explained in Patent No. 255,023, dated March 14, 1882, and which improvements are hereinafter fully described, and the novel features thereof specified in the claims hereunto annexed.

My improved apparatus for uniting wood for floor-coverings is represented in the accompanying drawings, in which-- Figure 1 is a plan view. Fig. 2 is a side view. Fig. 3 is a section on the dotted line as 00, Figs. 1 and 4. Fig. 4. is an inverted view. Fig. 5 is a plan view with the platen removed or swung upward. Fig. 6 is a section on the dotted line y y, Figs. 1, 4, and 5. Fig. 7 is a section on the line 2 2, Fig. 5. Fig. 8 repre sents the sliding plate which releases the clamp-bar from its latch. Fig. 9 is a detached view of one of the toggles. Fig. 10 is a partial plan view showing the grooved bar through which the molten metal may be introduced. Fig. llis a section on the line y Fig. 10. Fig. 12 is a partial sectional view on the longitudinal axis of one of the toggles, showing a modification.

My improved apparatus for uniting blocks for floor-coverings consists, essentially, of a bed, A, provided on two of its adjoining sides with projecting ribs d d, a clamp-bar, B, platen 0, movable presser-bars c c, and lever D, for operating the presser-barsby means of the toggles '0 o, the whole apparatus being so constructed and, arranged that an assemblage of grooved blocks, E E, Fig. 5, may be firmly held or clamped on all sides between the bed and the platen, and between the pressenbars and the projecting ribs on the bed, and the blocks while in this position may be fastened together by the injection of 'molten metal or suitable alloy into the grooves; and for this purpose it is necessary that the platen should be made removable from the bed, in order to permit the introduction or assembling of the blocks on the bed and the removal of the leaded square, that mechanism should beprovided to press the platen forcibly against the bed, and that the blocks while on the bed should be subjected to pressure laterally in both directions, in order to secure close joints between the sides of the blocks. The bed A, which may be of any suitable size or shape adapted to the largest assemblage of blocks which it is designed to fasten together by the use of the apparatus, is provided with the ribs (1 d, which may be either cast with it or secured thereto in any preferred manner. The inner surfaces of these ribs should be squared with each other. The platen 0 should be made large enough to cover the largest assemblage which the apparatus is designed to take in. The platen may be provided with the stiffening-ribs b b, Fig. 1, and it may be attached to the bed by means of the hinges g g. At its center it is provided with a boss, f, against which the screw 3, carried by the clamp-bar B, presses, in order to force the blocks E against the bed. The bar 13 is attached to the bed so that it can be removed therefrom for the purpose of affording access to the blocks.

In the accompanying drawings l have represented the clamp-bar as hinged at one end, at h, to the bed, the other end being arranged to be held by a spring or other catch, by which it is secured in place and a resistance offered to the pressure applied to the platen by the screw z and handle j. The springcatch Z, Figs. 2, 3, and 4, is arranged to slide in a suitable opening or slot in the bed A, its end being beveled, so that the end m of the bar B will force the catch back when the bar is swung from B to B, Figs. 2 and 5, after which the catch Z is forced outward by the spring n, Fig. 4, toengage in a notch or hole in the end of the bar. By turning the handle j, the screw 6 is then caused to press the platen against the assemblage of blocks 011 the bed. A lever, Figs. 2 and 3, is pivoted to the clamp bar, by which the slide is forced downward, the end of which, coming in contact with the beveled end of the catch Z, forces it into the bed and releases the clampbar from its engagement therewith.

Any other suitable means of detaehably connecting the clamp-bar with the bed may, however, be employed.

As represented in Fig. 6, the platen is hinged to the bed by pins passing through slots in the lugs h, or otherwise loosely connected thereto, so as to allow the platen to be forced against the blocks by the screw 1'.

In order to secure the proper contact between the sides of the blocks, I place between the bed and the platen the sliding presserbars 6 e, which are arranged to move forward and backward on the bed, as represented by the full and dotted lines in Fig. 5, while remaining parallel to the opposite ribs, d d. The bar a is connected through suitable slots in the bed With the sliding frame a" by means of the arms 26 t. The frame r is rectangular in shape, and arranged to slide to and fro in suitable ways on the lower side of the bed formed by the ribs 8 s, Fig. 4. A reciprocating motion is given to the frame r by means of the lever D and toggle c, as indicated by the full and dotted lines in Fig. 5. The lever D is pivoted to the bed on the pivot a, Figs. 3 and 4, the outer end of the pivot being sustained by a brace, 0, if necessary, fastened to the bed. The lever is provided at its inner end with an enlargement, w, Fig. 4, which contains two sockets for the reception of the cylindrical bosses on the ends of the toggles m2. The head of the lever is provided on one or both sides with the plates or washers x 00', Fig. 4, attached by screws thereto, by which the rounded ends of the toggles are held in place in the sockets formed for them in the head. The edges of the sockets are cut away in such shape as to permit the angular movement of the body of the toggle when the lever D is moved, as indicated by the full and dotted lines in Fig.

4. The outer end of the toggle v is fitted in a similar socket in the inner edge of the crossbar of the frame r, being kept in place by the washer It will thus be perceived that by swinging the lever D from D to D, Fig. 4, the toggle-joint will be straightened out, forcing the frame 1 to slide along the bed, and carrying the presser-bar c with it, thereby clamping or forcibly pressing all the blocks in the square together and against the rib (Z. A similar movement is transmitted to the frame 1'' by the movement of the lever D operating the toggle v, and causing the frame 7' to slide in suitable ways on the bed at right angles with the direction of movement of the frame r. The frame r is connected with the presscr-bar e by the arms t t, Fig. 5, so that the movement of the frame is transmitted to the bar, which forces the blocks against the rib d. One of the frames may be arched over the other to permit the sliding movement of the latter, as represented at 70 In, Figs. 2 and 4. Either or both of the sliding frames 1' 1 may be secured in place on the bed by suitable gibs, V, Fig. 4, attached to the bed by screws or bolts. The bed may be provided with the studs or pivots L L on opposite sides, by which the apparatus is sustained in any suit able table or other Support, P, Fig. 1, so that it may be swung from the horizontal to the vertical or an inclined position, for the purpose of facilitating the operation of introducing the lead or alloy into the grooves around the wooden blocks. A lever, N, is attached to the bed, by which it may be swung from one position to the other, the lever being arranged to operate in connection with a springcatch, R, or other analogous device,by which the apparatus is held in the horizontal position to permit the introduction of the blocks and the removal of the leaded square. On the inner surface of one of the ribs d, or of a metallic bar attached thereto,is formed 9.- Ion gitudinal groove, g, which is so placed as to come opposite the grooves in the sides of the blocks, and through which the fused metal or alloy is introduced. The groove q, communicates, near its middle,preferably, with an opening, 0, in the rib, into which the molten metal is poured or forced by any suitable apparatus. A pivoted sprue-cutter, T, having an orifice which comes opposite the hole 0 in the rib, serves to remove any projecting metal by being turned upward, as represented by the dotted lines in Fig. 2, and the metal in the groove (1 and opening 0 is removed with the square of blocks, being afterward dressed down true in any preferred manner.

The method of operating my improved apparatus for joining wooden blocks will have been already understood from the foregoing description. The grooved wooden blocks, of any preferred size and shape, are assembled together on the bed, which is preferably, for convenience, at this time held in the horizontal position, and pressure is applied to them laterally in each direction by means of the presser-bars ee, operated by the lever D, suit able wooden or metal packing being introduced between the edges of the square of blocks and the presser-bars, if required. The platen O is then brought down on the blocks, the clamp-bar swung over and secured to the bed by the catch Z, or equivalent device, and the platen forced against the blocks by the screw t. The apparatus is now, for convenience, swung from the horizontal to the vertical position, and the molten metal poured or forced into the opening c,whence it almost instantly finds its way through the groove q into the grooves between the blocks, and, becoming solidified therein, firmly unites the blocks together into sections suitable for use as floorcoverings or for other purposes.

It is obvious that the molten metal may be introduced through an opening in the platen,

the presser-bars, or the bed, suitable arrangements being made to insure the entrance of the metal into the grooves about the blocks.

My improved apparatus may be employed for uniting grooved blocks of any material suitable for floor-coverings or wall-ornamentation. It may also be employed in forming sections of other than the rectangular form herein shown, by using suitably-shaped packing between the presser-bars and the sides of such sections.

A grooved bar, i, maybe used between the edges of the assemblage of blocks and the rib d, as represented in Figs. 10 and 11, the bar being provided on its innerside with a groove, q, communicating with the opening through which the molten metal is introduced.

It is obvious that any suitable device or devices may be substituted for the lever and toggles herein described-such, for instance, as a cam, or two screws, or two screws connected together by bevel gears.

My improved apparatus, without the opening for the introduction of molten metal, may be used for gluing or otherwise cementing cloth, 8m, to one surface of the assembled blocks, and for similar purposes.

My invention is restricted to the combinations herein specifically claimed, the other novel features herein shown having been invented by Oharles E. Rider, of Rochester, New York.

I claim- 1. In combination with the bed-plate A,having ribs dd, presser-bars e e, platen O, the

frames r17, toggles o o, and lever D, substan- HENRY BEISHEIM.
